Hello! Welcome to the forums! Thanks for your post.
In relation to your concerns on when Zcashd will be turned off. The ecosystem follows a 16 week EOL cadence for full node versions so under normal circumstances you should expect that once teams signal that no one needs to depend on Zcashd any longer, then adequate time needs to be provided to the ecosystem to migrate their software to the new stack while factoring in this 16-week cadence.
This means that this won’t be the last Zcashd version but yes its last network upgrade.
As I’ve mentioned in the previous posts our timeline shifted due to the awesome user attention that price action brought to the ecosystem. So, although you are not early, you are still not late to provide feedback on your requirements for the migration path. We kindly request that you test Zallet and let us know how it could better serve your needs.
So we can safely work on Zebra + Zallet integration and testing without worrying that zcashd support will end before Zallet is production-ready, correct?
We’ll start testing Zallet and provide feedback on any issues or missing RPC methods we encounter.
Hello from ZkAV Club’s recording station at sub0 polkadot conference in Buenos Aires. It’s awesome to receive fellow Zcashers here. We are heading into a major privacy event on Sunday and an incredible week at DevConnect. Meanwhile, another week, another Zcash Z3 update.
All campaigns start to intertwine, but that’s fine. NU 6.1 Full node operator outreach is going fine and 6.3.0 EOL passed without us hearing much fuzz about it which tends to be a good sign. We are doubling down on wallet operators, specially transparent ones so they modify the custom Bitcoin libraries they use for transparent ZEC before November 23rd. Zallet Alpha is getting more attention and we continue to get feedback on it as well as the Z3 containerized stack ZF is maintaining.
Zebra
ZF engineers are preparing Zebra 3.0.0’s official release and also supporting the Zallet Alpha outreach when it comes to questions about the Z3 containerized stack.
Zingo folks continue wrapping up the chain index work, block explorer support and fighting against some testing tooling issues. Zaino is also getting updated to work with Zebra 3. On a separate line of work, I keep helping out with the transparent data for light clients implementation between constant pings from the outreach campaigns.
Last week I talked to you about this board. It is now fully prioritized. If you want to contribute to Zallet just pick the github issue you like the most and get hacking, that’s it!
Meanwhile ECC folks are back at it and integrating the Zaino chain index work and providing feedback to Zingo colleagues. Zallet sync engine is being prepared to get more work done.
Hello! It’s been a crazy week at DevConnect. A lot of Zcash appreciation. Zk AV club has recorded around 16 hours of footage. Meanwhile, another week, another Zcash Z3 update.
Outreach
Status: In progress
Outreach has been more passive online just monitoring NU 6.1 updates on wallets and exchanges that we are in touch with and more active in person at DevConnect.
Zebra
The Zebra team has released version 3.0.0. According to ZF’s post
Zaino folks are wrapping up migration to Zebra 3 while chain index work continues while other folks attend DevConnect. I continue to refactor zaino light client protocol interface as part of the transparent data support work.
Part of the ECC team is on a on-site team meeting. We haven’t seen much movement on the repo.
Although I want to stress out that last week I talked to you about this board. It is now fully prioritized. If you want to contribute to Zallet just pick the github issue you like the most and get hacking, that’s it!
The Zebra adaptation of Zcash Block explorer will be moved to production soon. On the other hand, we haven’t progressed much on this front and the same status of last week remains.
Hello! Last Monday was a big date for everyone! Another Network Upgrade successfully carried out by all the people and organizations in our ecosystem. Congratulations to ZF, ECC, Zingo, Shielded Labs, ZCG and all of you who collaborated sending your reports and statuses. We can’t also neglect the other big date on Tuesday where coinholders voted on retroactive grants proposals. All of this is happening! Also, it’s Thanksgiving in some countries and Zcashers are celebrating with their loved ones. Happy Thanksgiving to those who celebrate. Meanwhile, another week, another Zcash Z3 update.
Outreach
Status: In progress
We did a quick run through to catch any last minute team that wasn’t aware of NU 6.1 and got a lot of thumbs up. In terms of Z3, we are getting good feedback from teams trying out the Z3 docker files that ZF put together.
Zebra
The Zebra team has released version 3.1.0 with some fixes around ARM docker support, mempool optimization and maximum size of RPC responses.
Zaino folks continue working on the chain_state feature and incorporating feedback from ECC core devs. You can track this work here. Also transparent data support progress can be tracked here
Zallet has received collaborations from external contributors and also improvements on the CLI usage, for example to support user and password authentication. Foundational work for sync engine revamp has been merged. wohoo!
The Zcash block explorer needed some maintenance due to NU 6.1 and new influx of transactions. Also, Zebra adaptation of Zcash Block explorer continues and will be moved to production soon. On the other hand, we haven’t progressed much on this front and the same status of last week remains.
NU 6.1 outreach came to an end… Let the NU 6.1 retrospective survey begin!!! We have a commitment with continuous improvement of the Zcash Developer Experience. For that we are reaching out to our partners to let them tell us what went good, what went wrong and how we can make things better for them. I published the results of the NU friction survey that was carried out Q3 2025.
Zebra
ZF did a lot of work around Zebra and released two consecutive versions around NU 6.1. They tell you more about it in their ZF engineering update.
In terms of Zaino, Zingo folks continue to develop the chain index refactoring with feedback from ECC. I finished the Transparent data support and I’m waiting for review from Zaino folks. In the meantime I’ll keep working on parity with the latest add-ons on lightwalletd.
This week we updated the collaboration board. The issues you see there are good collab opportunities and sorted by relevance. Str4d and Kris are preparing new alpha builds that are going to be out soon. Some partners have been testing the migration from Zcashd workflow and the next alpha will have fixes for those partners to test.
